3Power Indicator: This LED will be illuminated in orange when the unit is in the Standby mode to signal that the unit is ready to be turned on. When the unit is in operation, the indicator will turn blue.

4Headphone Jack: This jack may be used to listen to the AVR’s output through a pair of head- phones. Be certain that the headphones have a standard 6.3 mm stereo phone plug. Note that the main room speakers and all Preamp Outputs will automatically be turned off when the headphone jack is in use.

5Surround Mode Group Selector: Press this button to select the top-level group of surround modes. Each press of the button will select a major mode grouping in the following order:

Dolby Modes ➜ DTS Digital Modes ➜ DSP Modes ➜ Stereo Modes ➜ Logic 7 Modes

Once the button is pressed so that the name of the desired surround mode group appears in the on-screen display and in the Lower Display Line ˜, press the Surround Mode Selector 9 to cycle through the individual modes available. For example, press this button to select Dolby modes, and then press the Surround Mode Selector

9to choose from the various mode options.

6Speaker Selector: Press this button to begin the process of configuring the AVR for the type of speakers it is being used with. For com- plete information on configuring the speaker set- tings using the front-panel controls see page 33.

7 ‹ Button: When an adjustment is being made using the Channel Select Ù or Digital Select Û buttons, this button may be pressed to scroll through the available options.

When the button is pressed so that the words TONE IN appear in the Main Infor- mation Display ˜, the settings of the Bass and Treble controls and of the Balance control will affect the output signals. When the button is pressed so that the words TONE OUT appear in the Main Information Display ˜, the output signal will be “flat,” without any balance, bass or treble alteration, no matter how the actual Controls are adjusted. (For more infor- mation, see page 41).
